Over the past year, pop surrealist Mark Ryden has tackled an unlikely new medium: ballet. Ryden designed the sets and costumes for the new American Ballet Theatre production “Whipped Cream.” The so-called “two-act confection” is based off the Richard Strauss-penned libretto “Schlagobers,” which was first performed in 1924 by the Vienna State Opera.The show kicks off on March 15 at Segerstrom Center for the Arts in Costa Mesa.
